The testo temperature measuring strips are self-adhesive, temperature-sensitive films that react with color change to certain temperature excesses. They are ideal for temperature monitoring of products and processes that do not need to exceed a specific temperature, e.g. for moving or small objects such as PCBs, for long-term monitoring during storage and transport, in the laboratory, in motor vehicle technology or in air and space travel.The temperature measurement strips are supplied in a 10-piece booklet. They can be easily detached like stickers from the handle and stick on the object to be measured.On the temperature measurement strips you can see a temperature scale from +37 °C to +65 °C, which is divided into white boxes. As soon as a certain temperature point is exceeded, the temperature gauge in the relevant boxes will be colored within 2 to 3 seconds. The temperature steps can be read as follows: 37°, 40°, 43°, 46°, 49°, 54°, 60° and 65° C.The color is irreversible: Once the
